Grove of Dreams

The Grove of Dreams connects to Route 9, and has 3 big trees, a regular tree, a water tree, and a fire tree. There is a house, the man inside will give you Leftovers. On the rock wall behind the regular tree is some vines, and there is a secret tunnel area you can walk through which leads to the fabeled ancient ruins explorers in the area have been looking for. If you walk up to the shrine and stand in the middle during the night and say, I wish for Jirachi, a cutscene will happen and a battle with be initiated with a level 25 Jirachi. Remember that you only have 1 chance to catch it, so save right before and if you kill it accidentially you can rejoin and try again. Around the fire tree is a caved-in mineshaft with what appears to be Registeel's eyes above it, which hints to a chance to capture Registeel in the future.
